Bangabandhu Satellite-1 will be deployed into a geostationary transfer orbit (GTO) approximately 33 minutes after launch.

The Bangabandhu Satellite-1 mission will be the first to utilize Falcon 9 Block 5, the final substantial upgrade to SpaceX’s Falcon 9 launch vehicle. Falcon 9 Block 5 is designed to be capable of 10 or more flights with very limited refurbishment as SpaceX continues to strive for rapid reusability and extremely high reliability.

Following stage separation, SpaceX will attempt to land Falcon 9’s first stage on the “Of Course I Still Love You” droneship, which will be stationed in the Atlantic Ocean.

The creation of a hybrid rocket motor system for SpaceShipTwo represented a significant engineering challenge. We are particularly proud that we designed and now test and manufacture this world class motor in house. Come meet the team behind the burn…the Rocket Guys.

To see deeper into space, we will need much bigger telescopes.

As astronomy seeks to find and study distant planets and peer further and more accurately into space and time, the limitations of ground based telescopes, especially optical telescopes, represents our largest barrier. Today we will examine what those limitations are, and ways to make vastly more enormous telescopes and arrays

Developed from HOTOL (Horizontal Take-Off and Landing) project
Skylon is a series of designs for a single-stage-to-orbit spaceplane by the British company Reaction Engines Limited (REL), using SABRE, a combined-cycle, air-breathing rocket propulsion system. The vehicle design is for a hydrogen-fuelled aircraft that would take off from a purpose-built runway, and accelerate to Mach 5.4 at 26 kilometres (16 mi) altitude (compared to typical airliners’ 9–13 kilometres (6–8 mi)) using the atmosphere’s oxygen before switching the engines to use the internal liquid oxygen (LOX) supply to take it into orbit.
